PLoS Blogger Steve Silberman published an interview with synaesthete Perry Hall. Hall has created an App called Sonified that allows the less-synaesthetic among us to experience a morphing of the senses. In related news, veteran Times columnist Matthew Parris wrote in the paper this week that he's experienced synaesthesia all his life, but only just discovered that the condition has a name, and that his experiences aren't shared by everyone.
